Finding the right slipper is more difficult than you'd think. In fact, it's like the opposite of Cinderella.
They tried that slipper on hundreds of girls before finding the perfect fit. I've tried hundreds of slippers, but never quite discover my idea of perfection.
This is a very British thing, I know. The rest of the world probably thinks we're weird using footwear to spank naughty bottoms with, but in the days of school CP it was the entry-level spanking implement of choice at most schools.
So it is very much part of my spanko psychology. You misbehave, you go to fetch the slipper. The problem is that in my experience you just can't get slippers that do the job properly.
Now if you haven't tried it, a good slipper punishment is quite something. For me it's as satisfying as good fast food - other meals may be closer to art, but fast food is just what you need when you need it.
A good slipper smarts like the devil, reddens efficiently and makes a big, scary sound. It doesn't leave much in the way of marks (good if you're off to the pool tomorrow) and it is an innocent object to have sitting around the bedroom, although a pair is less likely to raise suspicions than just the one.
But not every slipper has it in it to be a spanking slipper. Many are called, but few make the grade. Most are way too light and have been made using the wrong sorts of materials.
For me it has to be a thick rubber sole with a smooth surface and just the right amount of upper - not too much, not too little. Plimsolls and sports shoes are so wrong, as are anything suede or with man-made fur on it.
In my experience it's easier to find a sandal that packs a good spank, but then a sandal isn't really a slipper, is it? Eventually, I'm sure I will go to the ball - I'll find the slipper that is exactly the one of my dreams... and in the meantime it is a good excuse to go to shoe shops.
